# Check the links in technical documentation

**Use case:** 

Documentation links to specifications, repositories and other docs, and those move more often than the prose does. Retries are limited so a slow server is not hammered, and a timeout is reported as a timeout rather than as a 404.

## Input

```json
{
  "startUrls": [
    {
      "url": "https://developer.mozilla.org/en-US/docs/Web/HTTP/Status"
    }
  ],
  "urls": [],
  "checkInternal": true,
  "checkExternal": true,
  "maxLinks": 60,
  "concurrency": 5,
  "perHostConcurrency": 2,
  "respectRobots": true,
  "timeoutSecs": 20,
  "maxRetries": 3
}
```

## Output

```json
{
  "url": {
    "label": "URL",
    "format": "string"
  },
  "state": {
    "label": "State",
    "format": "string"
  },
  "httpStatus": {
    "label": "Status",
    "format": "integer"
  },
  "reason": {
    "label": "Reason",
    "format": "string"
  },
  "naiveCheckWouldSayBroken": {
    "label": "Naive check would call this broken",
    "format": "boolean"
  },
  "method": {
    "label": "Method used",
    "format": "string"
  },
  "headRejectedStatus": {
    "label": "HEAD rejected with",
    "format": "integer"
  },
  "redirectCount": {
    "label": "Redirects",

  },
  "finalUrl": {
    "label": "Final URL",

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/neverempty/link-checker.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
